Description

【０００１】
【発明の属する技術分野】
本発明は、通信サービス提供システムに用いられ、既存通信サービス制御装置から新通信サービス制御装置に設備更新する場合に、サービス停止なしに既存通信サービス制御装置に登録されているサービス契約者データを新通信サービス制御装置に移行するサービス契約者データ移行方式に関する。
【０００２】
【従来の技術】
現在の通信サービス提供システムでは、サービス提供を受ける契約者が任意のタイミングでＰＢ（プッシュボタン）音やインターネット等を利用したカスタマコントロールすることによって、契約者の登録データ（以下、契約者データ）の内容を更新することが可能である。また移動体通信の位置情報のように、契約者通信端末が移動することによって自動的に更新されるデータもある。
【０００３】
ところで、既存設備から新設備に設備更改する場合、契約者毎に固定的に設定されたデータに加えて、上記のように任意のタイミングで変更されるデータについても最新のデータを引き継ぐ必要がある。このため、従来では、任意のタイミングで変更されるデータを考慮し、設備更改時に一時的に通信サービスを停止し、既存設備の契約者データベースから契約者データを収集し、新設備にデータを移行した後、新設備にルーチングを切り替えるのが一般的である。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記のような従来の方式では、契約者データの移行中は、通信サービスを一時的に停止しなければならない、契約者データの変更ができない、契約者データを既存設備側で変更できても新設備に引き継がれない等の課題があった。
【０００５】
本発明は上記の課題を解決し、サービス契約者データのデータ移行中であっても、通信サービスを継続させることができ、さらに契約者データの変更が可能で、その変更を新設備に引継することのできる通信サービス提供システムのサービス契約者データ移行方式を提供することを目的とし、さらにその方式を実現する上で必要となる新通信サービス制御装置、既存通信サービス制御装置及び交換機、新通信サービス制御装置に用いられるサービス契約者データ移行処理方法及びそのプログラムを提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、本発明に係る通信サービス提供システムのサービス契約者データ移行方式は、以下のような特徴的な構成を有する。
【０００７】
（１）それぞれ通信網に接続され、すでに通信サービスを提供している１または複数の既存通信サービス制御装置と、これから通信サービスを提供する新通信サービス制御装置と、サービス契約者端末が収容される１または複数の交換機とを備え、前記既存及び新通信サービス制御装置は、それぞれ前記交換機に収容されたサービス契約者端末を管理するためのサービス契約者データを登録するデータベースを備え、いずれかの交換機からサービス契約者端末宛の呼接続要求があったとき、前記データベースを参照して該当する交換機に接続先を指示する通信サービス提供システムに用いられ、前記既存通信サービス制御装置から前記新通信サービス制御装置に設備更新する場合に、前記既存通信サービス制御装置のデータベースに登録されているサービス契約者データを前記新通信サービス制御装置のデータベースに移行するサービス契約者データ移行方式において、前記通信網に接続される交換機に対して、前記サービス契約者データの移行前に、サービス契約者端末宛の呼接続のルーチング先を前記既存通信サービス制御装置から前記新通信サービス制御装置に切り替えるように設定しておき、前記新通信サービス制御装置が、前記交換機からの呼接続要求に応じて、前記既存通信サービス制御装置からサービス契約者データを取得して自装置内のデータベースに登録するとともに、当該データに基づいて通信サービスを継続して呼接続先に提供することを特徴とする。
【０００８】
（２）前記既存通信サービス制御装置は、前記新通信サービス制御装置からのデータ取得要求時に、その要求に該当するサービス契約者データを自装置内のデータベースから検索し、検索結果を返送する要求応答手段を有することを特徴とする。
【０００９】
（３）前記１または複数の交換機の少なくともいずれかが、前記サービス契約者データを登録するデータベースを備え、前記既存通信サービス制御装置とともに分散してサービス契約者データを管理しているとき、前記新通信サービス制御装置は、前記交換機からの呼接続要求に応じて、前記既存通信サービス制御装置及び交換機から該当するサービス契約者データを取得し、前記既存通信サービス制御装置からの契約者データと前記交換機からの契約者データと間の論理矛盾判定を行い、論理矛盾がない場合は、自装置内のデータベースに登録するとともに、当該データに基づいて通信サービスを継続して呼接続先に提供し、論理矛盾がある場合は、登録を取りやめるとともに、呼接続要求を呼損とすることを特徴とする。
【００１０】
（４）前記サービス契約者データを登録するデータベースを備える交換機は、前記新通信サービス制御装置からのデータ取得要求時に、その要求に該当するサービス契約者データを自装置内のデータベースから検索し、検索結果を返送する要求応答手段を有することを特徴とする。
【００１１】
（５）前記新通信サービス制御装置は、前記サービス契約者端末への呼接続要求があったときに、すでに自装置内のデータベースに該当するサービス契約者データが登録されているか否かを判別し、登録されていない場合のみデータ取得を行って、契約者単位にデータ移行の完了の有無を管理することを特徴とする。
【００１２】
（６）前記新通信サービス制御装置は、オペレータからの保守コマンド入力に応じて前記既存通信サービス制御装置または交換機からサービス契約者データの取得を行う手動処理手段を備えることを特徴とする。
【００１３】
すなわち、本発明に係る通信サービス提供システムのサービス契約者データ移行方式では、契約者データを既存通信サービス制御装置から新通信サービス制御装置にデータ移行する前に、呼接続のルーチング先を新通信サービス制御装置に切り替え、呼接続がある度に既存通信サービス制御装置にデータ取得を行い、その契約者情報で通信サービスを継続するとともに、新通信サービス制御装置のデータベースに契約者情報を書き込む。
【００１４】
また、通信サービスの内容によっては、１つの通信サービス制御装置だけでなく他の通信サービス制御装置や交換機のデータベースに契約者データが分散されて登録されている場合も想定されるので、呼接続契機に複数の通信サービス制御装置や交換機のデータベースにデータ取得する機能を有する。
【００１５】
一度契約者データを移行したユーザから再度アクセスがあった場合は、新通信サービス制御装置内のデータベースのみを参照し、既存通信サービス制御装置にはアクセスしないようにする。データ移行期間中に契約者からまたは契約者への呼接続がないことも想定されるため、新通信サービス制御装置に対して強制的に既存通信サービス制御装置にデータ取得に行く手段も用意し、移行対象の契約者データを新通信サービス制御装置に移行する。
【００１６】
従来の方法では、一時的にサービスを停止し、サービス停止前の契約者データを引き継ぐか、データ移行期間中に任意のタイミングで更新される契約者データについては、引き継がれないかのどちらかであった。また、サービス提供条件も契約者データを既存通信サービス制御装置から新通信サービス制御装置にデータ移行している間は、既存通信サービス制御装置で提供し、データ移行後、新通信サービス制御装置にルーチングを切り替えるのが一般的であった。
【００１７】
既存通信サービス制御装置でサービスを提供しながらデータ移行する場合に、上記のように任意のタイミングで更新される契約者データがあった場合は、更新されるたびに新通信サービス制御装置のデータを更新する必要があり、新通信サービス制御装置側は、データ移行が終了したことを判断することが困難であった。
【００１８】
（１）または（３）の構成により、まずルーチング先を既存通信サービス制御装置から新通信サービス制御装置に切り替えることによって、ルーチング切り替え後の特定契約者への最初のアクセスで契約者データを移行してしまい、（５）の機能を利用してその後の同一契約者への呼接続については既存通信サービス制御装置へのアクセスをなくすことが可能となる。よって新通信サービス制御装置では契約者データの有無でデータ移行が終了したことを判断することが可能となる。また（６）の機能を用いて、呼接続が発生しない契約者のデータも移行することが可能となる。
【００１９】
上記データ移行方式を実現する上で、本発明は、さらに以下のような特徴的な構成を備える新通信サービス制御装置、既存通信サービス制御装置及び交換機、新通信サービス制御装置に用いられるサービス契約者データ移行処理方法及びそのプログラムを提供する。
【００２０】
（１）のシステムに用いられる新通信サービス制御装置は、前記交換機からの呼接続要求に応じて、前記既存通信サービス制御装置からサービス契約者データを取得するデータ取得手段と、この手段で取得されたサービス契約者データを自装置内のデータベースに登録するデータ登録手段と、前記データ取得手段で取得されたサービス契約者データに基づいて通信サービスを継続して呼接続先に提供するサービス継続処理手段とを具備することを特徴とする。
【００２１】
（３）のシステムに用いられる新通信サービス制御装置は、前記交換機からの呼接続要求に応じて、前記既存通信サービス制御装置及び交換機から該当するサービス契約者データを取得するデータ取得手段と、この手段で取得された前記既存通信サービス制御装置からの契約者データと前記交換機からの契約者データと間の論理矛盾判定を行う判定手段と、この手段の判定結果で、論理矛盾がない場合には取得された契約者データを自装置内のデータベースに登録し、論理矛盾がある場合は、登録を取りやめるデータ登録手段と、前記判定手段の判定結果で、論理矛盾がない場合には取得された契約者データに基づいて通信サービスを継続して呼接続先に提供し、論理矛盾がある場合には呼接続要求を呼損とするサービス継続処理手段とを具備することを特徴とする。
【００２２】
上記新通信サービス制御装置のデータ取得手段は、前記サービス契約者端末への呼接続要求があったときに、すでに自装置内のデータベースに該当するサービス契約者データが登録されているか否かを判別し、登録されていない場合のみデータ取得を行って、契約者単位にデータ移行の完了の有無を管理することを特徴とする。
【００２３】
また、上記新通信サービス制御装置は、さらにオペレータからの保守コマンド入力に応じて前記既存通信サービス制御装置または交換機からサービス契約者データの取得を行う手動処理手段を備えることを特徴とする。
【００２４】
（１）のシステムに用いられる既存通信サービス制御装置は、前記新通信サービス制御装置から前記データ取得要求を受け取り、その要求に該当するサービス契約者データを自装置内のデータベースから検索し、検索結果を前記新通信サービス制御装置に返送する要求応答手段を有することを特徴とする。
【００２５】
（３）のシステムに用いられる交換機は、前記新通信サービス制御装置から呼接続要求に応じて該当するサービス契約者データを取得するためのデータ取得要求が出されたとき、このデータ取得要求を受け取り、その要求に該当するサービス契約者データを自装置内のデータベースから検索し、検索結果を前記新通信サービス制御装置に返送する要求応答手段を有することを特徴とする。
【００２６】
（１）のシステムの新通信サービス制御装置に用いられるサービス契約者データ移行処理方法は、前記交換機からの呼接続要求に応じて、前記既存通信サービス制御装置からサービス契約者データを取得するデータ取得ステップと、このステップで取得されたサービス契約者データを自装置内のデータベースに登録するデータ登録ステップと、前記データ取得ステップで取得されたサービス契約者データに基づいて通信サービスを継続して呼接続先に提供するサービス継続処理ステップとを具備することを特徴とする。
【００２７】
（３）のシステムの新通信サービス制御装置に用いられるサービス契約者データ移行処理方法は、前記交換機からの呼接続要求に応じて、前記既存通信サービス制御装置及び交換機から該当するサービス契約者データを取得するデータ取得ステップと、このステップで取得された前記既存通信サービス制御装置からの契約者データと前記交換機からの契約者データと間の論理矛盾判定を行う判定ステップと、このステップの判定結果で、論理矛盾がない場合には取得された契約者データを自装置内のデータベースに登録し、論理矛盾がある場合は、登録を取りやめるデータ登録ステップと、前記判定ステップの判定結果で、論理矛盾がない場合には取得された契約者データに基づいて通信サービスを継続して呼接続先に提供し、論理矛盾がある場合には呼接続要求を呼損とするサービス継続処理ステップとを具備することを特徴とする。
【００２８】
上記新通信サービス制御装置に用いられるサービス契約者データ移行処理方法のデータ取得ステップは、前記サービス契約者端末への呼接続要求があったときに、すでに自装置内のデータベースに該当するサービス契約者データが登録されているか否かを判別し、登録されていない場合のみデータ取得を行って、契約者単位にデータ移行の完了の有無を管理することを特徴とする。
【００２９】
また、上記新通信サービス制御装置に用いられるサービス契約者データ移行処理方法は、さらにオペレータからの保守コマンド入力に応じて前記既存通信サービス制御装置または交換機からサービス契約者データの取得を行う手動処理ステップを備えることを特徴とする。
【００３０】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を詳細に説明する。
【００３１】
（第１の実施形態）
図１は本発明の第１の実施形態における通信サービス提供システムの構成を示すブロック図である。図１において、１１…１ｎは１番目乃至ｎ番目の既存通信サービス制御装置、２は新規に設置される新通信サービス制御装置であり、これらは通信網３に接続されている。通信網３には、複数（ここでは２台）の交換機４１、４２が接続されている。交換機４１には発信端末５が収容され、交換機４２にはサービス契約者端末６が収容されているものとする。
【００３２】
本実施形態では、既存通信サービス制御装置１ｉ（ｉは１乃至ｎのいずれか）のデータベースＤＢに登録されている契約者データαを新通信サービス制御装置２のデータベースＤＢにデータ移行する方式を説明する。
【００３３】
図２は本実施形態における通信サービス制御の一例を示すシステム図、図３はその通信処理の流れを示すシーケンス図、図４はそのときの新通信サービス制御装置２で行われる処理方法と処理プログラムの概要を示すフローチャートである。
【００３４】
本実施形態では、既存通信サービス制御装置１ｉの契約者データαを新通信サービス制御装置２にデータ移行する前に、交換機４１、交換機４２のルーチング先を既存通信サービス制御装置１ｉから新通信サービス制御装置２に切り替える（行程Ａ１）。この行程Ａ１は、既存機能で実現可能な行程である。ルーチング先を新通信サービス制御装置２に切り替えた後に、発信端末５から交換機４１にサービス契約者端末６への呼接続要求があった場合（行程Ａ２）、交換機４１は、通信網３経由で新通信サービス制御装置２にルーチングする（行程Ａ２′）。
【００３５】
新通信サービス制御装置２は、自装置内のデータベースＤＢにサービス契約者端末６の契約者データαが存在するか否かを検索し、契約者データがない場合、既存通信サービス制御装置１ｉに契約者データαを取得に行く（行程Ａ３）。
【００３６】
このとき、新通信サービス制御装置２と既存通信サービス制御装置１ｉとの間の接続ルートは、通信網３経由で実施してもよいし、インターネット網等を利用してもよい。データ取得の信号は、通信網６経由の場合は、新通信サービス制御装置２と既存通信サービス制御装置１ｉ間で規定されている信号であればよく、例えばＩＮＡＰ（Intelligent Network Application Protocol：ＩＴＵ−Ｔ標準）のような標準的な信号方式であっても、通信網３内の独自規定の信号方式であってもよい。インターネット網等を利用する場合も、インターネット網で規定されているファイル転送方式等を利用すればよい。
【００３７】
ただし、契約者データを取得した後、呼接続を継続する必要があるため、短期間でデータを取得できる手段である必要がある。また、呼接続要求は、サービス契約者端末６から交換機４２、通信網３経由であってもよく、契約者データを参照する機会のある呼接続要求であれば、発信・着信等の呼種は問わない。
【００３８】
データ取得要求信号を受信した既存通信サービス制御装置１ｉは、自装置内のデータベースＤＢを参照して、契約者データ中の番号から契約者データαを検索し、データ取得結果信号にマッピングして新通信サービス制御装置２に返送する（行程Ａ４）。データ取得結果信号を受信した新通信サービス制御装置２は、自装置内の契約者データベースＤＢにデータを登録し、契約者データαを参照して、呼接続を継続するために交換機４１に接続先を指示する（行程Ａ５）。この指示を受けた交換機４１は、交換機４２に呼接続要求を行い（行程Ａ６）、交換機４２はサービス契約者端末６に着信要求を出す（行程Ａ７）。
【００３９】
このときの新通信サービス制御装置２では、図４に示すように、交換機４１からの指示依頼を受けると（Ｓ１１）、契約者番号の有無を判定し（Ｓ１２）、なければ契約者番号の登録されている既存通信サービス制御装置１ｉを特定して（Ｓ１３）、その既存装置１ｉに対してデータ取得要求を出す（Ｓ１４）。
【００４０】
次に、既存通信サービス制御装置１ｉからのデータ取得結果を受信する（Ｓ１５）。ここで、データ取得結果の受信が成功したか失敗したかを判別し（Ｓ１６）、失敗した場合にはステップＳ１４に戻ってデータ取得要求を再出力する。成功した場合には、自装置内のデータベースＤＢに取得したサービス契約者データを登録し（Ｓ１７）、交換機４１に接続指示を出力する（Ｓ１８）。また、ステップＳ１２において、契約者番号があった場合には、既にデータ移行が完了しているので、ステップＳ１８に移行し、接続指示を出力する。
【００４１】
すなわち、上記構成による契約者データ移行方式では、契約者データを既存通信サービス制御装置１ｉから新通信サービス制御装置２にデータ移行する前に、呼接続のルーチング先を新通信サービス制御装置２に切り替え、呼接続がある度に既存通信サービス制御装置１ｉにデータ取得を行い、新通信サービス制御装置２のデータベースＤＢに契約者データを書き込むとともに、その契約者データで通信サービスを継続する。
【００４２】
このとき、一度契約者データを移行したサービス契約者端末宛に再度アクセスがあった場合は、新通信サービス制御装置２内のデータベースＤＢのみを参照し、既存通信サービス制御装置１ｉにはアクセスしない。以後、契約者データの変更があった場合には、新通信サービス制御装置２で対応することができる。
【００４３】
したがって、上記構成による契約者データ移行方式によれば、契約者データの移行中であっても、通信サービスを継続させることができ、さらに契約者データの変更が可能で、その変更を新設備に引継することができる。
【００４４】
（第２の実施形態）
本実施形態では、第１の実施形態の構成に加えて、交換機４２内の契約者データベースＤＢに登録されている契約者データβも新通信サービス制御装置２にデータ移行する方式を説明する。
【００４５】
図５は本発明の第２の実施形態における通信サービス提供システムの構成を示すブロック図である。図５において、図１と同一部分には同一符号を付して示し、ここでは重複する説明を省略する。
【００４６】
本システム構成は、図１に示した第１の実施形態のシステム構成に加え、交換機４２内にデータベースＤＢを設け、当該交換機４２に収容されているサービス契約者端末６の契約者データの一部をそのデータベースＤＢに登録して、既存通信サービス制御装置１ｉとともに分散して管理するようにしたものである。
【００４７】
図６は本実施形態におけるサービス制御の一例を示すシステム図、図７はその通信処理の流れを示すシーケンス図、図８はそのときの新通信サービス制御装置２で行われる処理方法と処理プログラムの概要を示すフローチャートである。図６乃至図８においても、図２乃至図４と同一部分には同一符号を付して示し、重複する説明を省略する。
【００４８】
本実施形態では、新通信サービス制御装置２において、既存通信サービス制御装置１ｉへの契約者データαのデータ取得終了後（行程Ａ４）、交換機４２内のデータベースＤＢへの契約者データβのデータ取得を行い（行程Ａ３′，Ａ４′）、その後、自装置内のデータベースＤＢを更新した後、呼接続を継続するために、交換機４１に接続先を指示する（行程Ａ５）。
【００４９】
このとき、新通信サービス制御装置２と交換機４２との間の接続ルートは、通信網３経由で実施してもよいし、インターネット網等を利用してもよい。データ取得の信号は、通信網３経由の場合は、新通信サービス制御装置２と交換機４２間で規定されている信号であればよく、ＩＮＡＰ（？）のような標準的な信号方式であっても通信網内の独自規定の信号方式であってもよい。また既存サービス制御装置へのデータ取得と同一の信号方式であっても異なる信号方式であってもよい。インターネット網等を利用する場合もインターネット網で規定されているファイル転送方式等を利用すればよい。
【００５０】
ただし、契約者データを取得後、呼接続を継続する必要があるため、短時間でデータ取得できる手段である必要がある。また、契約者データαと契約者データβの取得の順番が入れ替わったとしても本方式は有効である。
【００５１】
新通信サービス制御装置２内の処理フローも、既存通信サービス制御装置１ｉにデータ取得に行くまでは、第１の実施形態の図４と同様である（Ｓ１１〜Ａ１６）。その後、図７のシーケンス例のとおり、交換機４２に対してデータ取得要求を行い（Ｓ２１）、当該交換機４２から契約者データβのデータ取得結果を受信する（Ｓ２２）。そして、データ取得結果について成功したか否かを判別し（Ｓ２３）、失敗している場合にはステップＳ２１から処理をやり直し、成功している場合には、取得した契約者データαと契約者データβの間で論理の矛盾がないかチェックを行う（Ｓ２４）。
【００５２】
例えば、通信サービスの一時停止状態のフラグを、契約者データαと契約者データβの両方で管理しており、契約者データαでは一時停止状態のフラグが一時停止中になっていて、契約者データβでは一時停止状態のフラグが解除状態になっていたと仮定する。この場合、新通信サービス制御装置２では、どちらのデータを使用してよいかわからない。そこで、契約者データα、β間で論理矛盾が生じているときは、データの登録を取りやめることにし（Ｓ２５）、呼接続も呼損とする（Ｓ２７）。このような場合、運用上で支障が生じるので、実際にはオペレータへ警告メッセージを出力したり、データ不整合のデータベースに登録したりして、オペレータへのデータ補正を促す機能を追加する（Ｓ２６）。
【００５３】
すなわち、上記構成による契約者データ移行方式では、既存通信サービス制御装置１ｉと交換機４２とで契約者データを分散して管理しているときでも、新通信サービス制御装置２にて呼接続がある度に既存通信サービス制御装置１ｉ及び交換機４２の両方から契約者データを取得し、両者の間で論理矛盾がないときにみ自装置内のデータベースＤＢに登録し、論理矛盾があるときは登録を取りやめて、警告メッセージを出力し、オペレータに注意を促すようにしている。
【００５４】
したがって、上記構成による契約者データ移行方式によれば、契約者データの分散管理を行っている場合でも、契約者データの移行処理を的確に行うことができ、新通信サービス制御装置２の運用にすみやかに移すことが可能となる。特に本方式は、既存通信サービス制御装置１ｉでサービスを提供しつつ、新通信サービス制御装置２でもサービス提供している場合において、装置間の機能分担が変更になるような場合に有効である。
【００５５】
（第３の実施形態）
本実施形態は、第２の実施形態に加え、図５に示すシステム構成において、図６に示すように運用処理がなされる場合に、データ移行期間中に呼接続が発生しない契約者の契約者データを、既存通信サービス制御装置１ｉから新通信サービス制御装置２に強制的にデータ移行するための方式である。
【００５６】
図９は、本実施形態における通信処理の流れを示すシーケンス図である。新通信サービス制御装置２からオペレータが強制的でデータ取得を行うためのコマンドを投入したときに、第１の実施形態や第２の実施形態と同様のデータ取得手順でデータ取得を行う。
【００５７】
すなわち、オペレータが強制データ取得要求を新サービス制御装置２に出力すると（行程Ｂ１）、新サービス制御装置２は自装置内のデータベースに該当する契約者データがあるか検索し、契約者データがなければデータ取得要求を既存通信サービス制御装置１ｉに出力し（行程Ｂ２）、当該装置１ｉから契約者データαのデータ取得結果を受け取る（行程Ｂ３）。次に、交換機４２にも同じデータ取得要求を出力し（行程Ｂ４）、当該交換機４２から契約者データβのデータ取得結果を受け取る（行程Ｂ５）。両契約者データα及びβを比較し、論理矛盾がなければ自装置内のデータベースＤＢに登録し、論理矛盾がある場合には登録を取りやめ、警告メッセージを発生して、この強制データ取得結果をオペレータに通知する（行程Ｂ６）。
【００５８】
図１０は、本実施形態の新通信サービス制御装置２で行われる処理方法と処理プログラムの概要を示すフローチャートである。図１０において、図８と同一部分には同一符号を付して示す。
【００５９】
この場合、データ取得の契機が、呼接続契機からオペレータのコマンド起動契機（Ｓ３１）に変更になり、強制データ取得完了をオペレータに通知する機能（Ｓ３２）を追加しただけで、データ取得・登録の行程は第１の実施形態の図４や、第２の実施形態の図８と同様である。尚、コマンドでの契約者番号を指定する場合や、契約者番号の範囲指定を行い、１番号毎に契約者データの有無を判定しながら順次データ取得を行う方法などがあり得る。
【００６０】
本実施形態は、第１の実施形態または第２の実施形態と組み合わせて運用することにより、契約者データの移行漏れを回避することが可能となる。
【００６１】
【発明の効果】
以上述べたように本発明によれば、まずルーチング先を既存通信サービス制御装置から新通信サービス制御装置に切り替えることによって特定契約者への最初のアクセスで契約者データを移行してしまい、呼接続を継続することによってサービス中断なしでのデータ移行が可能となる。また、その後の同一契約者への呼接続については既存通信サービス制御装置へのアクセスをなくすことが可能となり、新通信サービス制御装置では契約者データの有無でデータ移行が終了したことを判断することが可能となる。
【００６２】
またオペレータがコマンド投入することによって、呼接続が発生しない契約者データも強制的に移行することが可能となり、データの移行漏れもなくすことが可能となる。
【００６３】
したがって、サービス契約者データのデータ移行中であっても、通信サービスを継続させることができ、さらに契約者データの変更が可能で、その変更を新設備に引継することのできる通信サービス提供システムのサービス契約者データ移行方式を提供することができる。

(3) When at least one of the one or a plurality of exchanges includes a database for registering the service contractor data and manages the service contractor data in a distributed manner together with the existing communication service control device, The communication service control device acquires corresponding service contractor data from the existing communication service control device and the exchange in response to a call connection request from the exchange, and the contractor data from the existing communication service control device and the exchange If there is no logical contradiction between the contractor data from the client and if there is no logical contradiction, it is registered in its own database and the communication service is continuously provided to the call destination based on the data. When there is a contradiction, the registration is canceled and the call connection request is a call loss.
[0010]
(4) When the exchange having a database for registering the service contractor data retrieves the service contractor data corresponding to the request from the database in the own apparatus when the data acquisition request is received from the new communication service control apparatus, A request response means for returning the result is provided.
[0011]
(5) When there is a call connection request to the service contractor terminal, the new communication service control device determines whether or not the service contractor data corresponding to the database in the own device has already been registered. The data acquisition is performed only when it is not registered, and whether or not the data migration is completed is managed for each contractor.
[0012]
(6) The new communication service control device includes manual processing means for acquiring service contractor data from the existing communication service control device or an exchange in response to a maintenance command input from an operator.
[0013]
That is, in the service contractor data migration method of the communication service providing system according to the present invention, the call connection routing destination is transferred to the new communication service before the contractor data is transferred from the existing communication service control device to the new communication service control device. Switching to the control device, every time there is a call connection, data is acquired to the existing communication service control device, the communication service is continued with the contractor information, and the contractor information is written in the database of the new communication service control device.
[0014]
In addition, depending on the content of the communication service, it may be assumed that the contractor data is distributed and registered not only in one communication service control device but also in other communication service control devices and exchange databases. In addition, it has a function of acquiring data in a plurality of communication service control devices and exchange databases.
[0015]
When the user who has once transferred the contractor data accesses again, only the database in the new communication service control device is referred to, and the existing communication service control device is not accessed. Since it is also assumed that there is no call connection from the contractor to the contractor during the data migration period, a means for forcibly obtaining data to the existing communication service control device is also prepared for the new communication service control device, The contractor data to be migrated is migrated to the new communication service control device.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0031]
(First embodiment)
FIG. 1 is a block diagram showing a configuration of a communication service providing system according to the first embodiment of the present invention. In FIG. 1, 11... 1 n are first to n-th existing communication service control devices, 2 is a new communication service control device newly installed, and these are connected to the communication network 3. A plurality (two in this case) of exchanges 41 and 42 are connected to the communication network 3. It is assumed that the exchange 41 accommodates the transmission terminal 5 and the exchange 42 accommodates the service contractor terminal 6.
[0032]
In the present embodiment, a method for transferring the contractor data α registered in the database DB of the existing communication service control device 1i (i is any one of 1 to n) to the database DB of the new communication service control device 2 will be described. To do.
[0033]
2 is a system diagram showing an example of communication service control in this embodiment, FIG. 3 is a sequence diagram showing the flow of communication processing, and FIG. 4 is a processing method and processing program executed by the new communication service control device 2 at that time. It is a flowchart which shows the outline | summary.
[0034]
In this embodiment, before transferring the contractor data α of the existing communication service control device 1i to the new communication service control device 2, the routing destination of the exchange 41 and the exchange 42 is changed from the existing communication service control device 1i to the new communication service control. Switch to device 2 (step A1). This process A1 is a process that can be realized by the existing function. After switching the routing destination to the new communication service control device 2, when there is a call connection request from the calling terminal 5 to the exchange 41 to the service contractor terminal 6 (step A <b> 2), the exchange 41 is updated via the communication network 3. The communication service control device 2 is routed (step A2 ').
[0035]
The new communication service control device 2 searches the database DB in its own device for whether or not the contractor data α of the service contractor terminal 6 exists. If there is no contractor data, the new communication service control device 2 contracts with the existing communication service control device 1i. Person data α is obtained (step A3).
[0036]
At this time, the connection route between the new communication service control device 2 and the existing communication service control device 1i may be implemented via the communication network 3, or the Internet network or the like may be used. The data acquisition signal may be a signal defined between the new communication service control device 2 and the existing communication service control device 1i via the communication network 6, for example, INAP (Intelligent Network Application Protocol: ITU-T). Standard signal system such as (standard) or a uniquely defined signal system in the communication network 3 may be used. In the case of using the Internet network or the like, a file transfer method defined by the Internet network may be used.
[0037]
However, since it is necessary to continue the call connection after acquiring the contractor data, it is necessary to be a means capable of acquiring the data in a short period of time. The call connection request may be from the service contractor terminal 6 via the exchange 42 and the communication network 3. If the call connection request has an opportunity to refer to the contractor data, the call type such as outgoing / incoming call is It doesn't matter.
[0038]
Receiving the data acquisition request signal, the existing communication service control device 1i refers to the database DB in its own device, searches for the contractor data α from the number in the contractor data, maps it to the data acquisition result signal, and creates a new one. It returns to the communication service control apparatus 2 (process A4). The new communication service control device 2 that has received the data acquisition result signal registers the data in the contractor database DB in the own device, refers to the contractor data α, and connects to the exchange 41 to continue the call connection. (Step A5). Upon receiving this instruction, the exchange 41 makes a call connection request to the exchange 42 (step A6), and the exchange 42 issues an incoming call request to the service contractor terminal 6 (step A7).
[0039]
In the new communication service control device 2 at this time, as shown in FIG. 4, upon receiving an instruction request from the exchange 41 (S11), the presence or absence of a contractor number is determined (S12). The existing communication service control device 1i that has been set is identified (S13), and a data acquisition request is issued to the existing device 1i (S14).
[0040]
Next, the data acquisition result from the existing communication service control device 1i is received (S15). Here, it is determined whether the reception of the data acquisition result is successful or unsuccessful (S16), and if it fails, the process returns to step S14 to re-output the data acquisition request. If successful, the service contractor data acquired is registered in the database DB in the own apparatus (S17), and a connection instruction is output to the exchange 41 (S18). In step S12, if there is a contractor number, the data migration has already been completed, so the procedure proceeds to step S18 and a connection instruction is output.
[0041]
That is, in the contractor data migration method with the above configuration, the call connection routing destination is switched to the new communication service control apparatus 2 before the contractor data is migrated from the existing communication service control apparatus 1i to the new communication service control apparatus 2. Every time there is a call connection, data is acquired in the existing communication service control device 1i, the contractor data is written in the database DB of the new communication service control device 2, and the communication service is continued with the contractor data.
[0042]
At this time, when access is made again to the service contractor terminal to which the contractor data has been transferred once, only the database DB in the new communication service control device 2 is referred to and the existing communication service control device 1i is not accessed. Thereafter, when there is a change in the contractor data, the new communication service control device 2 can cope with the change.
[0043]
Therefore, according to the contractor data migration method configured as described above, the communication service can be continued even while the contractor data is being migrated, and the contractor data can be changed. Can be taken over.
[0044]
(Second Embodiment)
In the present embodiment, in addition to the configuration of the first embodiment, a method for transferring the contractor data β registered in the contractor database DB in the exchange 42 to the new communication service control apparatus 2 will be described.
[0045]
FIG. 5 is a block diagram showing a configuration of a communication service providing system according to the second embodiment of the present invention. In FIG. 5, the same parts as those in FIG. 1 are denoted by the same reference numerals, and redundant description is omitted here.
[0046]
In this system configuration, in addition to the system configuration of the first embodiment shown in FIG. 1, a database DB is provided in the exchange 42, and a part of the contractor data of the service contractor terminal 6 accommodated in the exchange 42 is provided. Are registered in the database DB, and distributed and managed together with the existing communication service control apparatus 1i.
[0047]
FIG. 6 is a system diagram showing an example of service control in the present embodiment, FIG. 7 is a sequence diagram showing the flow of communication processing, and FIG. 8 is a processing method and processing program executed by the new communication service control device 2 at that time. It is a flowchart which shows an outline. 6 to 8, the same parts as those in FIGS. 2 to 4 are denoted by the same reference numerals, and redundant description is omitted.
[0048]
In the present embodiment, in the new communication service control device 2, after the data acquisition of the contractor data α to the existing communication service control device 1i is completed (step A4), the data acquisition of the contractor data β to the database DB in the exchange 42 is obtained. (Process A3 ', A4'), and thereafter, after updating the database DB in the own apparatus, in order to continue the call connection, the exchange 41 is instructed the connection destination (process A5).
[0049]
At this time, the connection route between the new communication service control device 2 and the exchange 42 may be implemented via the communication network 3 or the Internet network or the like may be used. The data acquisition signal may be a signal defined between the new communication service control device 2 and the exchange 42 when the communication network 3 is used. INAP (?) Even a standard signal system such as the above may be a signal system uniquely defined in the communication network. Further, it may be the same signal system as the data acquisition to the existing service control apparatus or a different signal system. When using the Internet network or the like, a file transfer method or the like defined by the Internet network may be used.
[0050]
However, since it is necessary to continue the call connection after acquiring the contractor data, it is necessary to be a means capable of acquiring the data in a short time. Even if the order of obtaining the contractor data α and the contractor data β is switched, this method is effective.
[0051]
The processing flow in the new communication service control device 2 is the same as that in FIG. 4 of the first embodiment until data is acquired by the existing communication service control device 1i (S11 to A16). Thereafter, as in the sequence example of FIG. 7, a data acquisition request is made to the exchange 42 (S21), and the data acquisition result of the contractor data β is received from the exchange 42 (S22). Then, it is determined whether or not the data acquisition result is successful (S23). If the data acquisition result is unsuccessful, the process is repeated from step S21. If it is successful, the acquired contractor data α and the contractor data are determined. It is checked whether there is a logical contradiction between β (S24).
[0052]
For example, the suspension flag of the communication service is managed by both the contractor data α and the contractor data β. In the contractor data α, the flag of the suspension state is suspended, and the contractor In the data β, it is assumed that the flag of the pause state is in the released state. In this case, the new communication service control device 2 does not know which data may be used. Therefore, when there is a logical contradiction between the contractor data α and β, the registration of the data is canceled (S25), and the call connection is also a call loss (S27). In such a case, there is a problem in operation, so a function for prompting the operator to correct the data by actually outputting a warning message to the operator or registering it in a data mismatch database is added (S26). ).
[0053]
That is, in the contractor data migration method having the above configuration, even when the contractor data is distributed and managed by the existing communication service control apparatus 1i and the exchange 42, the new communication service control apparatus 2 has a call connection. The contractor data is acquired from both the existing communication service control apparatus 1i and the exchange 42, and is registered in the database DB in the own apparatus only when there is no logical contradiction between the two, and the registration is canceled when there is a logical contradiction. A warning message is output to alert the operator.
[0054]
Therefore, according to the contractor data migration method having the above configuration, even when contractor data is distributedly managed, the contractor data migration process can be performed accurately, and the new communication service control apparatus 2 can be operated. It becomes possible to move quickly. In particular, this method is effective in the case where the function sharing between devices is changed when the service is provided by the new communication service control device 2 while the service is provided by the existing communication service control device 1i.
[0055]
(Third embodiment)
In the present embodiment, in addition to the second embodiment, in the system configuration shown in FIG. 5, when an operation process is performed as shown in FIG. 6, a contractor who does not generate a call connection during the data migration period. This is a method for forcibly transferring data from the existing communication service control device 1i to the new communication service control device 2.
[0056]
FIG. 9 is a sequence diagram showing a flow of communication processing in the present embodiment. When the operator inputs a command for compulsorily acquiring data from the new communication service control device 2, data acquisition is performed according to the same data acquisition procedure as in the first and second embodiments.
[0057]
That is, when the operator outputs a compulsory data acquisition request to the new service control device 2 (step B1), the new service control device 2 searches for the contractor data corresponding to the database in the own device, and there is no contractor data. For example, a data acquisition request is output to the existing communication service control device 1i (step B2), and a data acquisition result of the contractor data α is received from the device 1i (step B3). Next, the same data acquisition request is output to the exchange 42 (process B4), and the data acquisition result of the contractor data β is received from the exchange 42 (process B5). Compares both contractor data α and β, and if there is no logical contradiction, registers it in the database DB in its own device. If there is a logical contradiction, cancels registration and generates a warning message. The operator is notified (step B6).
[0058]
FIG. 10 is a flowchart showing an outline of a processing method and a processing program performed in the new communication service control apparatus 2 of the present embodiment. 10, the same parts as those in FIG. 8 are denoted by the same reference numerals.
[0059]
In this case, the data acquisition trigger is changed from the call connection trigger to the operator command start trigger (S31), and only the function (S32) for notifying the operator of the completion of forced data acquisition is added. The process is the same as in FIG. 4 of the first embodiment and FIG. 8 of the second embodiment. There may be a method of specifying the contractor number with a command, a method of specifying the range of the contractor number, and sequentially acquiring data while determining whether or not there is contractor data for each number.
[0060]
By operating in combination with the first embodiment or the second embodiment, this embodiment can avoid omission of contractor data migration.
[0061]
【The invention's effect】
As described above, according to the present invention, the contractor data is first transferred to the specific contractor by switching the routing destination from the existing communication service control apparatus to the new communication service control apparatus. By continuing the operation, data migration without service interruption becomes possible. For subsequent call connections to the same contractor, it becomes possible to eliminate access to the existing communication service control device, and in the new communication service control device, it is determined that the data migration is completed based on the presence of contractor data. Is possible.
[0062]
In addition, when the operator inputs a command, it is possible to forcibly transfer contractor data in which no call connection occurs, and it is possible to eliminate omission of data transfer.
[0063]
Therefore, the communication service providing system can continue the communication service even during the data transfer of the service contractor data, can further change the contractor data, and can transfer the change to the new equipment. A service contractor data migration method can be provided.
